In fact, I made an estimate a while ago. It went something like this:
1. We have 20,000 registered FreeBSD users.
2. It's difficult to say how many people register, since there is no
requirement to do so. It could be as low as 0.1% of users.
3. This would imply that there could be up to 20,000,000 users of
FreeBSD. This is a best-case estimate.
4. Let's split the difference and say 10,010,000 users.
This means that we have 10,000 users more than Linux :-)
